Regearing Ecoboost After Level
So I just got a 2.5 inch level for my 2014 f-150 Ecoboost, and put 295/60 20 tires on it (34.5x12). After install I noticed a huge loss in power and acceleration. I have 3.55 gears right now, and trying to decide whether I should get 3.73, 4.10, or 4.56 gears. I don't care about gas mileage as much, but want a lot of power. Any suggestions would be great. Thanks

4.56:1
It will make up for the size increase AND the weight, rolling resistance increase.

If you don't care about gas mileage the 4.56's will take you over 100 mph. My 35 Toyo's measure closer to 34.5 . There are some great calculators online that you can use. Some let you put your trans gear ratios. Our trucks are at .60 gear in sixth. You are running an effective 325 gear in fourth gear (where it's 1:1). I got 4.10 gears and mine is now 3.88 effective in fourth. The 4.56 are an effective 4.12 gear . This is all with 34.5 in tires.
